non-polymorphic local table.
lazy load clause evaluation is plenty solid enough to handle it this time.
- the join_to() method on PropertyLoader takes the parent mapper as an argument and alisiazes
the primaryjoin against that mapper's selectable, so that the same primary join can be used against
the base mapper, any inheriting mapper, etc., whether or not it uses a polymorphic union (although
needs to be tested against alternate polymorphic unions added on subclasses). fixes [ticket:448]

further on that branch and introduce the foreign_keys argument, and further centralize the "intelligence" about the joins and selectables into PropertyLoader so that lazyloader/sync can be simplified, but the current branch goes pretty far.
- relations keep track of "polymorphic_primaryjoin", "polymorphic_secondaryjoin" which it derives from the plain primaryjoin/secondaryjoin.
- lazy/eagerloaders work from those polymorphic join objects.
- the join exported by PropertyLoader to Query/SelectResults is the polymorphic join, so that join_to/etc work properly.
- Query builds itself against the base Mapper again, not the "polymorphic" mapper. uses the "polymorphic" version
only as appropriate. this helps join_by/join_to/etc to work with polymorphic mappers.
- Query will also adapt incoming WHERE criterion to the polymorphic mapper, i.e. the "people" table becomes the "person_join" automatically.
- quoting has been modified since labels made out of non-case-sensitive columns could themselves require quoting..so case_sensitive defaults to True if not otherwise specified (used to be based on the identifier itself).
- the test harness gets an ORMTest base class and a bunch of the ORM unit tests are using it now, decreases a lot of redundancy.

- this is a wide refactoring to "attribute loader" and "options" architectures.
ColumnProperty and PropertyLoader define their loading behaivor via switchable
"strategies", and MapperOptions no longer use mapper/property copying
in order to function; they are instead propigated via QueryContext
and SelectionContext objects at query/instnaces time.
All of the copying of mappers and properties that was used to handle
inheritance as well as options() has been removed and the structure
of mappers and properties is much simpler and more clearly laid out.

replace the main table of the query, if the table is somewhere within
the given from_obj. this makes it possible to produce custom joins and
outerjoins in queries without the main table getting added twice.
[ticket:315]
- added join_to and outerjoin_to transformative methods to SelectResults,
to build up join/outerjoin conditions based on property names. also
added select_from to explicitly set from_obj parameter.
- factored "results" arrays from the mapper test suite and into the
"tables" mapper
- added "viewonly" param to docs
